With injuries piling up at tight end, the Seahawks added a pair of players at that spot, signing Jackson Harris and Wes Saxton. Tight ends Tyrone Swoopes and Justin Johnson were waived/injured to make room on the 90-man roster. 

Saxton went undrafted out of South Alabama in 2015 and appeared in one game with the New York Jets that season. He also spent time with Washington, Buffalo, Detroit and San Francisco, and most recently was with the Birmingham Iron of the Alliance of American Football.

Harris, an undrafted rookie out of Georgia, took part in Seattle's rookie minicamp as a tryout player.

Swoopes, who signed with the Seahawks as an undrafted rookie out of Texas in 2017, has spent most of the past two seasons on the practice squad. The former college quarterback appeared in one game each of the past two seasons, starting Seattle's win in London over the Raiders last year, a game in which he had a 23-yard reception that set up a touchdown.

Johnson, who signed with the Seahawks as an undrafted rookie out of Mississippi State in May, was injured during Thursday's practice and Seahawks coach Pete Carroll said at the time that it was likely an Achilles injury.

"I'm afraid he might have got an Achilles today," Carroll said Thursday. "Just one of those freaky injuries, he's out in space, takes a step and that pop happens… It's very unfortunate."
